Nothing wrong with your response. You need to be the one to decide when enough is enough. When you feel low, it is not time to react. It is time for a break.
For me, a couple of hours alone is all I need to get my mind back on track.
If H runs back to OW you can't act like it is OK. I would do what you suggested and maybe more. Depends on how ugly I felt like getting.
Don't spend much time worrying about this. Instead, sort thru what has been working and what has not. Do more of what has worked and try to think of some new stuff. Cut the "what has not worked" out of your reportoir.
